Craftsman mower

We have a Craftsman push mower with a 6.75hp Briggs & Stratton. It refused to start a while back and I replaced the spark plug..still nothing. So I removed the magneto, cleaned it and put it back together. It ran fine for 3 or 4 weeks, no problem starting it at all. Then it quit running again. I replaced the magneto today and it started right up first try, and second and refused to afterwards. I thought about taking the carburetor off & cleaning it or ordering a carb rebuild kit..not sure what my next step should be. Any ideas what is going on?

RE: Craftsman mower

here is one idea:
check the shut off switch that is controlled by the bale on the handlebar. Due to wear, weak linkage, or corroded cable, the contact may still be grounding the ignition.

2nd idea:
remove the air filter and examine the venturi tube while depressing the primer bulb. You should see fuel pumped from the float bowl. Sometimes, the gasket between the carburetor and air filter housing deteriorates and the primer bulb is not effective.

RE: Craftsman mower

When you are having the problem, check for spark.
IF you have spark, prime the carb with a couple teaspoons of gas and see if it fires.
That way you can isolate the problem to fuel or electrical.

Providing the engine Model & Type numbers would allow one to know WHICH Briggs you have.
Knowing which type of carb used simplifies things greatly.
